‘Rigorous’ probe into toddlers’ deaths: mayor

NEW YORK – Mayor Bill de Blasio says New York City is conducting a “rigorous” investigation into a “freak” radiator accident that led to the deaths of two toddler sisters. De Blasio said Thursday that a “pained silence” filled the air when officials visited the Bronx apartment where twoyear-old Ibanez Ambrose and her one-year-old sister, Scylee, were fatally injured. He said the officials were surrounded by signs of a “warm and loving household.” De Blasio said something happened with a radiator valve Wednesday, releasing an “extraordinary” amount of steam.
